VGA consoles can be set up to blank after a certain number of seconds
to protect the screen from excessive wear. The kernel parameter
TBLNK controls the VGA console screen protection feature.
By default, screen blanking is not performed:
to enable this feature,
log in as root and use the
configure(ADM)
command or the Hardware/Kernel Manager
described in
``Configuration tools'' in the Performance Guide.
Select category 9, ``TTY and console configuration''
and change
the value of TBLNK to the number of seconds that the system
should wait before blanking the screen. Then relink the kernel
as described in
``Relinking the kernel'' in the SCO OpenServer Handbook.
